WYATT BOYD, OF SABINA, OHIO.

CONNECTION FOB INFLATING TIRES.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed October 29, 1907. Serial No. 399,755.

To all whom it may concern:

Be it known that I, WYATT BOYD, a citizen of the United States, residing at Sabina, in the county of Clinton and State of Ohio, have invented a new and useful Connection for inflating Tires, of which the following is a specification.

This invention relates to hoseconnections for inflation valves and has for its object to provide a comparatively simple and inexpensive device of this character especially designed for attachment to an automobile, motor cycle or similar vehicle and by means of which the tires of the vehicle may be effectually inflated-while the latter is in motion.

A further object of the invention is to provide a supporting bracket having means for attachment to the spokes of a vehicle wheel and provided with a bell shaped annulus for the reception of an air conducting hose thereby to permit free rotation of the vehicle wheel without danger of cutting, abrading or otherwise injuring said hose.

A further object is to provide means for yieldably supporting the hose on the mud guard of the vehicle, said supporting means also serving to retain the mating sections of the hose swivel in contact with each other.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency as wellas to reduce the cost of manufacture.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure 1 is a side elevation of a portion of a vehicle provided with a hose connection constructed in accordance with my invention. Fig. 2 is a rear elevation partly in section of the same. Fig- 3 is a detail perspective view of the supporting bracket detached. Fig. 4 is a vertical sectional view of the hose swivel detached.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved device forming the subject matter of the present invention is principally designed for attachment to automobiles, motor cycles and similar vehicles and by Way of illustration is shown in connection with'a motor car of the ordinary construction in which 5 designates the body of the car, 6 the mud guard and 7 the traction wheel provided with a pneumatic tire, indicated at 8.

The attachment consists of a supporting bracket comprising a bar 9 having one end thereof rovided with a plurality of spaced sets of e amping arms 10 adapted to embrace the adjacent spoke of the wheel 7 and having its upper end deflected laterally and pro vided with a terminal bell shaped annulus or guide ring 1-1.

The bar 9 is secured to the vehicle wheel by means of a clamp 12 which embraces the bar between the clamping arms 10 and also the adjacent wheel spoke and is provided with an adjusting screw 13 by means of which the attachment may be locked in position on said wheel. I

Operatively connected with the valve 14 is one end of an air conducting hose 15 the intermediate portion of which is extended through the bell shaped annulus 11 while'its opposite end is secured to the depending stem of a swivel section 16. The swivel section 16 is provided with an enlarged head 17 which bears against an annular shoulder or seat 18 formed in the mating section 19, the latter being provided with exterior corrugations 20 for engagement with' an air conducting pipe 21. The pipe 21 is operatively connected with an air compressor of any suitable construction mounted on the automobile or motor car and operated by the latter so that the wheel tires may be inflated without the necessity of stopping the vehicle.

The tube 15 is yieldably suspended from the mud guard 6 by a coiled spring 21 one end of which is secured to a loop or eye 22 on the swivel section 19 while the. opposite end thereof is fastened in any suitable manner to said guard, as shown. The spring 21 forms a yieldable connection between the tube 15 and mudguard 6 so as to prevent injury to said tube when the vehicle is traveling over rough uneven roads. The spring 21 not only serves to prevent in'ury to the tube 15 but also serves to yieldably support the head 17 of the swivel section 16 1n engagement -with theshoulde'r 18 of the mating section so asto form a firm contact between the two and thus prevent the escape of air.

The interior walls of the annulus 11 at the enlarged end thereof are flared outwardly while the'interior walls of the annulus at the reduced end thereof are curved laterally so as to prevent the tube 15 from becoming cut or severed by contact with the annulus'when the wheel revolves.

In using the device the supporting bracket is positioned on one of the spokes of the vehicle with the annulus 11 s aced from and disposed concentric with the ub of the wheel after which the tube 15 is connected with the valve and thence passed through the annulus 11 for attachment to the stem of the swivel section 16, one or more convolutions 23 being formed in the flexible supply pipe 21 so as to allow for any longitudinal movement of the tube 15.

It will thus be seen that when the vehicle wheel is in motion the supporting bracket will revolve with the same and the bell 1 1 being disposed concentric with the axle of the vehicle will permitthe intermediate portion of the tube 15 to revolve'around the inclined wall of said annulus, any twisting or torsional movement of the tube, being prevented by the swivel section '16.

While the tube 15 is shown extended in a vertical plane for attachment to a mud guard it is obvious that the same may be arranged in a horizontal plane and attached to any other desired portion of the vehicle.

From the foregoing description it will be seen that there is provided an extremely sim-. ple, inexpensive and eflicient device admirably adapted for the attainm'ent of the ends in view.

Havingthus described the invention 'what is claimed is:

1. A connection-for inflation valves com prising a supporting bracket having means for attachment to a vehicle wheel and provided with an annulus, and a fluid conducting tube extending through said annulus and having one end thereof secured to the'valve thereof provided with means for attachment I to the spokes of a vehicle wheel and its 0pposite end provided with a bell" shaped annulus, a tube extending through the annulus and operatively connected with the valve, a supply pipe, and a swivel connection between the supply pipe and tube.

4. A connection for inflation valvesv comprising a bracket having one end thereof provided with a plurality of spaced sets of clamping arms adapted to embrace the adjacent spoke of a vehicle wheel and havingits opposite end extended laterally and rovided with-an annulus-the: interiorwal s of which are curved laterally, an-air'conduc'ting tube extending through-the annulus and operatively connected with the valve, a supply. pipe, and a swivel connection between the supply pipe and tube. 1

5. The combination with avehicle having a traction wheel and provided'w'ithan inflation valve, of .a sup ort'ing bracket secured to the wheel of tiie vehicle and provided with an annulus disposed concentric with the hubof the wheel, a fluid conductor extending throu h the annulus for connection with the va ve, a supply pipe, a swivel connection between the supply pipe and conductor, and means for suspending the .conductorfrom the vehicle.

6. The combination with a vehicle having a traction wheel provided with an inflation valve, a bracket having one end thereof provided withspaced arms adapted to embrace one of the spokes of the wheel andhaving its opposite end off set and provided with a terminal annulus disposed concentric with the hub of the wheel,- a clam embracing the bracket and the adj acent. spo e of the wheel, a swivel including mating sections one of which is provided with a laterally extending eye, a supply pipe secured to one of the sectrons of the swivel, an air conducting'tube secured to the other section of the swivel and having its intermediate portion extended through the annulus for attachment to the valve, and a spring secured to the eye of said swivel section and operatively con,-

nected with the vehicle.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence'of two witnesses.
